Last week, a jury found him guilty of seven rapes and 11 indecent assaults which took place between 1963 and 1979.

He was cleared of various sexual offences in relation to six other complainants.

Greater Manchester Police has confirmed they are now investigating fresh sex allegations against Teret made by four other women.

Detective Chief Inspector Graham Brock said: "After decades of hiding behind the veneer of being a distinguished radio presenter, Ray Teret has finally been exposed as the manipulative and dangerous sexual predator that he is."

He said Teret "cast a dark shadow" over his victims' lives, adding: "I know from speaking to them personally how devastating the effects of his abuse have been.

"They have courageously relived their ordeal at court and should be applauded for having the bravery to speak out and bring this man to justice for his appalling crimes.

"Since his trial began, we have received four new complaints about Teret and our officers will now be investigating these fresh allegations. For obvious reasons I cannot go into great detail about those complaints."
